I want to record some video of a person playing drums to different songs. Each song played will have its own video link on the web page, so if i have 3 songs recorded, there will be 3 links on the site. the drummer will have headphones on to listen to the song, but i want the viewers to hear the actual song and the drummer playing to it, how do i get the actual song that the drummer is listening to, to also be recorded? i just don't want the drums to be heard all by themselves, i want the song the drummer is listening to to also be heard!! do i use a webcam or some other type of video recorder?? and how about the sound?

You have to have the 2 audio streams separated. The only simple method is to mix the existing sound and use it as one channel and record the drummer as the other channel. You will need to balance the levels. You may record it with a video recorder or webcam, depending on your equipment and editing facilities.

can you tell me what equipment i would need? for example i know i need a video recorder and a cd player. how do i do this one channel two channel thing? do i need to connect the cd player to both video recorder, and to the drummers headphones? tc

The CD player output goes to a mixer to mix left and right. The mixed output goes to headphones and to 1 channel of the recorder. The drummer's mike goes to the other channel of the recorder.
